“On the 1999 mercury grand marquis ls 4.6 l v8 the original plastic intake manifold cracked and busted wide open causing all the coolant / antifreeze to pour out. From what I gather there was a recall on this years ago and they made a different intake manifold which was aluminum for the part that the thermostat goes into and the rest of it was plastic. If this isn't caught in time and all the fluid leaks out it will completely destroying your engine also. Mine cracked while it was in park just running.”Owner report · Engine · Apr 2019
